Retail delivery service Instacart is launching in the Chattanooga area July 20.

"Over the past year, we’ve seen incredible demand in the Chattanooga area," general manager Nick Friedrich said in a prepared statement. "Expansion into Chattanooga gives us an opportunity to expand service in the Tennessee market."

Instacart allows shoppers to pick items from stores such as Publix, Whole Foods, Costco and Petco and have them delivered in as little as an hour, according to a news release.

Service areas include Chattanooga, Red Bank, Soddy-Daisy, Lakesite, Ooltewah, East Brainerd, Tyner, Middle Valley, Falling Water, Metro Park, Alpine Heights, East Ridge, Signal Mountain, Lone Oak, Fairmount, Walden, Harrison, Ridgeside and Summer Haven. 

To order, customers go online or use a mobile app, which is available on iPhone and Android devices; select a city and store; and then add items to a virtual cart. Customers can order up to seven days in advance.

An Instacart shopper uses the app to accept the order and deliver the items in a designated time frame.

This process is similar to Shipt's, which is available in Chattanooga, but customers can only order from Publix through Shipt. 

"We work with a variety of local retailers to provide the freshest, highest-quality groceries to our customers," Friedrich also said. "We’re also excited to build a world-class shopper community, where we can offer fun and flexible jobs for our shoppers, who ultimately deliver this amazing service to the community."

First-time users can enter the code HICHATTA (expires Nov. 8) at checkout to get $25 off an order of $35 or more, plus free delivery.

Instacart is also offering customers a free year of Instacart Express membership, which includes free unlimited, same-day deliveries on orders over $35 (expires Aug. 3).

After the initial trial, the cost of Instacart Express membership goes up to $149 a year or $14.99 a month.
